To all whom it may concern.-

Be it known that I, REINERT OLsEN, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Jury-Rudders, of which the following is a specification.

My invention relates to substitute apparatus to be used in cases of accident to the rudders of ships and for other like purposes.

It consists in the combination of mechanism and in details of construction, which will be more fully explained by reference to the accompanying drawings, in which Figure l is a plan view of the stern of a ship with my improved jury-rudder. Fig. 2 is a side view of the same, and Fig. 8 is a detail plan view of the rudders.

In case of loss or accident to the rudder of a vessel it is extremely difficult to rig up any temporary apparatus by which the vessel can e steere It is the object of my'invention to provide an apparatus of this description which is always in readiness for use and which can be carried upon the deck of a vessel or in convenient position for immediate application.

A is a spar of sufficient strength having any suitable or desired length, dependent upon the height of the vessel above the water and the angle at which it is desired to set the apparatus when in use. At the outboard end of the spar rudders 2 are mounted. These rudders are shown as having pintles u on each side of the lower end of the spar. ne such rudder may be used but I have found that two rudders hung one upon each side of the spar produce very satisfactory results. The outer edges of the rudders are connected by chainsor wire ropes, as at 3.

The end of thespar projects between the rudders and is so shaped that when the rudders are turned as far as desired in one direction one of the rudders will contact against the end of the spar which projects between them, and thus limit the turning movement in that direction. When the rudders are turned in the opposite direction, the other rudder will make a similar contact. Thus the movement of the rudders will be made within a safe limit. d

The spar is fitted either by notching its under side or by forming a notch or stop in that portion of the vessel upon which the spar rests, as at 4, so that this point of rest may be prevented from slipping about when the other attachments are applied to hold the spar in place.

The inboard end of the spar may extend as far from the rail or sternof the vessel as desired and has around it a band or other equivalent means for attaching eyebolts 5, one of which is fixed upon each side of the inner end of the spar and another beneath the spar. From the side eyebolts 5 wire ropes or chains 6 extend diagonally rearward and down to the deck of the vessel, where they pass through and are made fast to other eye bolts 8,fixed firmly in the vessels deck or timbers. A similar rope or ropes 9 extend from the eyebolt at the under part of the spar, extend down to the deck, and connect with a centrally-fixed eyebolt 10. These ropes are designed to brace and steady the inner end of the spar. If the vessel is to be steered by a wheel or capstan, as at 11, a brace 12 may be fitted between the end of the spar and the capstantimbers, which rise from the deck and are strongly fixed. This gives a powerful and rigid support to the inner end of the spar. Near the lower and outer-end of the spar is a metal band 13 or equivalent means of attaching eyebolts 14, one of which is fixed upon each side of the spar and another below. Through these eyebolts other bracing-ropes 15 and 16 extend to the vessel, diverging so as to be secured to the eyebolts 17 and 18, suitably fixed to the vessel.

To the top of the outer end of the spar is fixed a strong metal strap 19, with means for attaching Wire ropes or chains 20. In the present case I have shown a heavy structure of timbers built upon the stern of the vessel, as at 21, the timbers being separated sufiiciently to allow the spar to pass between them, and ropes 20 from the attachment 19 pass over the top of this framework, thence down to the deck, where they are secured to eye or ring bolts 22, which are firmly fixed to the vessels deck.

The spar and rudders may ordinarily lie upon a deck-house or other convenient part of the vessel out of the way until needed.

The outboard connecting ropes or chains are so attached that they may be easily applied if not already in place, and the spar is then pushed outboard between the timbers of the framework 21 until it reaches the proper position. The outboard ropes are I shortened until there will be a substantially even tension upon them, and the inboard ropes being then drawn taut the spar will be firmly braced by these ropes, so that it will have little or no motion by reason of the ac tion of the sea.

As the spar is projected to a considerable distance away from the stern of the vessel, it will be seen that the rudders will have a greater leverage and effect in steering the vessel than a single rudder upon the sternpost. Consequently these rudders may be made smaller. From the outer sides of these two rudders tiller-ropes 23 extend through suitable guides or pulley-blocks, as at 24:, thence lead in the usual manner to the steering-wheel, wherever it may be located. If located near the stern of the vessel, as in the illustration, these ropes will be comparatively short; but if, as in the case of steamers, the wheel-house is in the front portion of the vessel, these ropes may be connected with the usual tiller-ropes at some point near the stern, and thus complete the communication with the steering-wheel.

The method of bracing the spar is especially important, since any desired tension may be brought upon the bracing ropes or chains and the spar held substantially rigid in its position.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. A steering apparatus for vessels consisting of a spar disposed in an inclined position with its inner end projecting inboard and its outer end extending into the water behind the vessel, said spar having rudders turnable upon its lower and outer end, and means by which the spar is rigidly connected with the vessel.

2. A steering apparatus for vessels consisting of a spar, means by which the spar is fixed in an inclined position, rudders turnable upon pintles at the lower end of the spar, said rudders having their rear edges connected and movable in unison, tiller-ropes connecting with the rudders and extending to the vessel, and a steering apparatus by which said ropes are manipulated.

3. A device for steering vessels consisting of a spar having eyebolts fixed near its outer and inner end, other eyebolts fixed to the vessel, ropes passing through the eyebolts of the spar and those upon the vessel to fix the spar in position, rudders having pintles upon each side of the lower end of the spar, connections between the rear edges of the rudders whereby they are movable in unison, and tiller-ropes connecting with the outer sides of the rudders, guides upon the vessel through which the tiller-ropes pass and a steering mechanism with which they are connected.

4. A steering apparatus for vessels consisting of a spar, a point of support intermediate between its ends whereby the inner end of the spar projects inboard, and the outer end extends into the water behind the vessel, ropes and eyebolts whereby the spar is secured in position, rudders pivoted in a substantially vertical position upon each side of the outer end of the spar, and flexible connections between the rear edges of the rudders, inclined faces upon the spar between the rudders, said faces forming contacts to limit the movement of the rudders in either direction and tiller-ropes extending from the rudders to a controlling mechanism upon the vessel.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

REINERT OLSEN.
